How this service works
Self-hosted personal-assistant paid tools via Lightning. Uses x402-shaped protocol (L402 lineage): HTTP 402 with a Lightning invoice in the response body + WWW-Authenticate header, retry with X-Payment-Hash: <hex> once paid. Results cached per payment_hash so legitimate retries don't cost twice.
Output
A list of up to 30 trending Hacker News stories, likely including titles, URLs, scores, and ranking metadata, returned as a JSON object after payment via Lightning invoice (x402 protocol).
Example use cases
Example prompt
“What are the top 15 trending stories on Hacker News right now? Pay for it if needed.”
Technical details
Endpoint
GEThttps://x402.wallace.us/x402/hackernews-trendingWhen to prefer
Use this endpoint when you need a quick, pay-per-call fetch of Hacker News trending stories without setting up a scraper or API key, and you're operating in an x402/L402 Lightning-payment-enabled agent environment. Prefer this over free alternatives when you want a self-hosted, privacy-respecting source with no rate-limit accounts required.
Side effects
- HTTP 402 returned if payment not yet made — requires paying Lightning invoice then retrying with X-Payment-Hash header
- Invalid n parameter (outside 1-30 range) may return an error or default to 10
- Payment hash not recognized or expired — requires initiating a new payment
- Upstream Hacker News API unavailable — service may return 5xx
- Cached result returned for same payment_hash on legitimate retry — expected behavior, not a failure
